This chapter focuses on selected aspects of relationships. It discusses the online dating, styles of romantic love, personality and sexual behaviour and coping with sexual problems. The chapter focuses on the issue of loneliness and what people might be able to do about it. It then focuses on owning pets as they frequently provide a daily source of relatedness, especially if people live alone. Online dating is a contemporary solution to the problem of getting enough human interaction. Online dating has great potential for good, but there are also risks and problems. Many sexual problems can be resolved by discovering what people do and do not like sexually and finding someone who shares at least some of those preferences or is willing to experiment. In October 2018, the United Kingdom government launched its strategy for tackling loneliness. This followed on from the campaign work that Jo Cox organised as an MP before she was murdered.
